Scuba Diving inside the Similan National park is the best diving in Thailand and one of the best in the world. There are numerous excellent dive sites. The fauna is very rich and you will spot, in addition to the usual reef fishes, many blacktip and Whitetip reef sharks. Leopard sharks are also very common in the marine reserve. The reef life is teeming with trigger fishes, unicornfishes and many other colourful fishes. Always keep an eye out for the pelagic fishes like barracudas and giant trevallies patrolling the area.
If you are lucky you can spot Manta rays flying around and even the biggest fish in the world the mythical Whale Shark!
The coral is also in great shape with a lot of table corals and staghorn coral. Soft coral is everywhere and very colourful. Most of the dive sites are filled with huge granite boulders which offer a fantastic playground for divers.
In addition, the Similans are very popular for underwater photography. The clear water, superb coral, rich fauna and the interesting topography will give you great photo opportunities on every dive site! Moreover you will find many macro subjects like Nudibranchs are all kind of small creatures.
Update September 2011: the dive site East of Eden is closed for coral regeneration as well as Islands number one, two and three.

How to dive Similan Islands?
Similan Islands are only accessible by liveaboard. You will cruise for 4 days to two weeks around this superb marine national park.
Read our article about the best Liveaboards in the Similan Archipelago.
It is possible in the same trip to also explore the Surin Islands marine reserve and the world famous dive site Richelieu Rock located a bit further North. Most of the Liveaboard leave from the city of Khao Lak situated North of Phuket. The Similan archipelago is situated only 50 km west. There are also Liveaboard leaving directly from Phuket and Ko Lanta. There are many liveboard options suitable for all budgets from the backpacker style to the luxury ones with private suite.
It is also possible to reach the Similans during a day trip from Khao Lak or Phuket but it will be a big day with more than 90 km to cover!
Another option is to camp on the islands. In some places tents and bungalow can be rented. You have to ask first to the National park headquarters in Taplamu or in a travel agency.
- These islands are a very popular diving destination, so be sure to book your trip in advance!
- In addition to your trip, you will also have to pay a national park entry fee of 400 Baht per person plus 200 Baht diving fee per day.

Best time to dive in Similan Islands
The national park is open from November 1st to April 30 but most of the liveaboards operate only from October to May. The best diving conditions occur in March with the best visibility and almost no wind.
- The peak diving season runs during the dry season from December to April. During this period you should book your Liveaboard well in advance!
Scuba Diving conditions
Diving conditions are usually very good with moderate current and good to very good visibility. Depending on the season it can range from 20 to 40 meters.
Water temperature is between 27°C to 30°C and you normally don’t even need a full wet suit.
Dive sites around the archipelago are suitable for divers from open water to divemasters and most of the diving is easy and quite shallow.
If you are planning an upcoming dive trip or travelling to Similan Islands, it is a really good idea to invest in travel insurance for scuba diving, because you never know what could happen and when you might need it (because accidents do happen!). I recommend this diving insurance as they offer worldwide coverage and focus on providing scuba divers a quality insurance and medical assistance service.
